Get Precise pH Readings with a Lab Grade Probe
The Atlas Scientific Lab Grade pH Probe is built for high-accuracy pH measurement in demanding lab and engineering work. It uses a double junction design and a Vanadium III tip to improve stability and reduce noise during measurement.
Atlas also highlights the Tyvek™ junction design, which helps hold internal electrolyte longer and supports longer periods between recalibration in the right applications.
Important: This is a probe only. You still need a compatible Atlas circuit, meter, or transmitter to read and process pH data.
Why you'll love it
- High accuracy probe: Built for precise pH measurement work
- Double junction design: Helps when measuring harder samples, including protein-rich solutions
- Stable readings: Vanadium III tip helps reduce noise and improve stability
- Wide pH range: Measures from 0 to 14 pH
- Fast response: Atlas lists 95 percent response in 1 second
What you can build
Use it for lab instruments, benchtop analyzers, water testing rigs, process prototypes, and any setup where accurate pH data matters.
Starter bundles
Pair it with an Atlas EZO pH circuit, carrier board, and proper calibration solutions for a complete pH measurement setup.
Recommended add-ons
Useful add-ons include pH 4, 7, and 10 calibration solutions, storage solution, probe mounts, cable adapters, and compatible Atlas pH electronics.

Pinout & usage notes
Connect the probe to compatible Atlas pH electronics, then calibrate with the proper pH buffers before use. The probe is intended for accurate measurement rather than simple hobby-only checks.
Because this is a probe-only product, plan for matching electronics, calibration solutions, and a suitable mounting method in your finished build.
